My Android phone is slow, how to fix it?

26 mayo, 2021

Nothing is immune to the passage of time, and our smartphones obviously are not. Whether it is the most powerful smartphone or any of the inexpensive ones, problems will end up appearing sooner or later, so we ask you: What is the most frequent failure you have suffered with your devices?

Well, surely most of you will be thinking the same thing as us, and that is the slowness that ends up appearing with use it is endemic to Android smartphones. However, this is not always due to major hardware errors, so it is very likely that you can solve it. We tell you how!

The slowness -or the lag, as it is called in English- it is not a bad thing that prevents us from using our phone, but it is true that among all the problems that weigh down the user experience, this is one of the most annoying. Have you ever thought about throwing your Android smartphone in the trash because of the slowness, right?

Well, they exist countless reasons that can lead us to suffer slowness in our smartphones, from the apps that stay in the background and with reserved resources, until the cache, which can get cluttered by installing, using, and uninstalling different apps over time.

As you can imagine, most easily solvable software problems. Let’s review.

If it is a hardware problem, it has a difficult solution …

If the slowness is due to the hardware, it will surely imply problems in the platform, either due to the chipset or memory, and we fear that you do not have a modular smartphone like your PC to replace the RAM or storage memory chip.

So that, if the problem is due to the hardware platform you will have a difficult solution and almost certainly you will have to change your smartphone, although there are things you can try before.

The first, it is important that on a smartphone with microSD slot for memory expansion, class or speed of this card is according to the capacity of the smartphoneSince today many applications use external memory to save data and if it does not work properly, reads and writes will slow down.

Likewise, if your phone is slow you should find out if the external memory is in good condition and works correctly. Simple to start right? Well let’s go to the software


Get used to closing recent apps

It is not that Android is not prepared to keep a multitude of applications open at the same time, in fact the operating system is ready for multitasking and has an automatic memory manager which will distribute resources more or less intelligently.

However, a good method to ensure the proper functioning of an Android device is get used to closing recent apps, and this is as simple as pressing the recent applications button and dragging your ‘cards’ to close them.

This will free up the resources reserved by the applications, and incidentally, you will make the entire hardware platform and the memory manager work less, which will no longer need to activate or deactivate the processes of each application as they request to do something.

Clear cache and unnecessary data

Android applications not only reserve resources when we install them, but they keep data in memory as we use them. This allows them to perform faster on common tasks, but in the long run weighs on device performance when the cache fills up.

Although the operating system itself deletes data, this can be forced in case your device is not working properly. It is not a complicated task, and to do it you can follow this tutorial that we published in Engadget Android back in the day.

What’s more, applications like WhatsApp usually automatically save a large number of files such as audio notes, photos, videos, etc., and this in many cases causes the device storage to fill up, slowing down its operation.

It is good to install a file manager and go around the folders of your Android system to delete data that you do not need, especially from these types of applications, and you must remember that for example the audio files will not appear in the galleries of the telephone.

Also, it is not at all counterproductive uninstall applications that we do not use also freeing up memory space and device resources.

If all this doesn’t work, reboot …

Well yes, we have reached the usual solution to all computer problems, and no, it’s not 42. If nothing works, restart your smartphone, this will force the applications to reload and will sometimes solve specific problems.

Obviously, the most radical solution is also the best, because if nothing has worked, surely you will have to save all the important data of the device on your computer and return to factory settings from the smartphone settings.

This is obviously the definitive solution to all kinds of software problems, as it returns the terminal to its original state and completely cleans the memory of the device.


And as a ‘bonus’, you can also think of a ROM …

I know, this is not a solution as such but only an option that Android users have, and that is if your device is very old and the manufacturer has stopped providing adequate support making the user experience insufferable, sometimes it will be good root the terminal and install a community ROM.

There are infinite options in the android scene, although the answer will surely be found in the xda-developers forums, the meeting place par excellence of most of the development teams of the Android platform.

And now we ask you, because surely you have ever suffered it. What have you done to solve the slowness of an Android device?
